My invention relates to portable machine tools, and more particularly to a portable work table equipped with various machine tools.

The object of my'invention is to provide a single. mobile unit incorporating 'a plurality of machine tools mounted thereon, in a manner whereby any single tool may be operated and used independently of the others.

Another object of my invention is to provide a unit of the character described supporting an actuating means accessible for actuating said machine tools one at a time.

Stillanother object of my invention is to'so' arrange the various machine tools on the work table, that one will not interfere with the other during their operation.

A further object of my invention is to construct a unit in a manner whereby each individual machine tool becomes a definite integral part of the portable work table. j

It is manifest to anyone familiar with the art, thathobbyists as well as home mechanics, have use for varied types of machine tools for different operations, and that it is often times impossibl and impractical to mount them independently and separately due to the lack of space or" mounting facilities. It is therefore advantageous to assemble the various machine tools onto a single work bench'that is mobile and may be moved from one location to theother for convenience, as well as making it possible to store the unit in an out-of-the-way location.

The device as illustrated, specified, and claimed herein is safe, sturdy, efficient and easy to manipulate, inasmuch as separate machine tools operate independently of each other.

Other and further objects of my invention will become more apparent as the description proceeds, when taken in conjunction with the drawings in which:

and referring now to the same. the'table top is identified by the character 20. This table top is horizontally disposed and mounted on a structural frame 2| consisting of vertical members,

longitudinal members, and lateral members. This structural frame 2| has also a lower frame 22 onto which are mounted a pair of wheels 23 at the forward end, and at the rearward end of. the lower frame 22 is shown a pair of skids 24" for frictional engagement with the floor to keep. the entire mobile structur from creeping or moving while the machine tools are being operat ed. The structural frame 2i is alsoprovidedwith a handle 25 pivotally attached at 26 to. the

frame 2| at the rearward end thereof. This" handle 25 may be folded vertically as shown in, Figure 1, or may extend outward in a horizontali position as shown in phantom in Figure 1. I

There is a horizontal shaft 2ljournalled in bearings 28 attached to the forward portion of the structural frame 2|.

This horizontal shaft 21 is provided with polishing or grinding wheels. shown as 29 at both'endsof the shaft 21, and j the shaft 21 is set low enough on the structural frame 2| so that the top of the wheels 29 will Q-notinterfere with the surface of the table top 20. This is shown-in Figures 3 and 4. There a steady rest or tool support '30 attached to the This support has a pivoted forward 1 portion 3| which is used to support the tools'or the like (not shown), and there is a guard 32' of semi-circular contour which is open at its; forward end '83 and has an angular bracket 34 equipped with a slot 35, and a bolt 36 is at-' tached to the frame structurejl, extending eurward therefrom through the slot 35 to permit frame 2 l.

the adjustment of the guard 32. These guards 32, obviously, are constructed in a right and left hand manner for mounting on the respective sides of the structural frame 2|.

There is another shaft 31 which is journalled in bearings 38 which are attached to the supports 2| forming an integral part of, and atattached to the bottom of the table top 20. This shaft 31 is shown with a circle saw 39 attached to its inwardly disposed end 40. The saw 39 extends upward through. a slot M1 in a plate 42, which plate is attached to the top of the table 20 by means of screws 43 or in any other convenient manner. I also show a guard lfl mounted on a link lever 45 which is supported by means of a vertical thin plate 46 extendingupward through the slot 4! in direct alignment with the saw blade 39, and permits the saw' to be used with safety, the guard member 44 raises and lowers according to the thickness of thework P4299. ein worksqqnf t ssha t t12@r provided with a'g'rooved ane-y shown as n, ich is a ttached to the shaft 3! at a point between i g ra o w H.

In Figures 6 and '7, I show the table 11 at tached to the tubular member 14. Obviously, as stated above, this tubular member may be a solid bar if desired. The table 11 in Eigures 6 and '7, is equipped with. a slide-memben 82* which has an angular member 83 vertically disposed on its upper face.

It is only necessaryto engage or disengage th belts from the pulleys in order to make the machine tool active or inactive, and only one tool at a time can be used. Obviously, the movement of the carriage 90 on the rails 89 will permit adjustment, and increasing or diminishing the tension of the belts as they are applied to the motor pulley shown as Ill. The adjustment of the various units is extremely simple, and the operation of the device does not require any mechanical skill as far as the engagement or disengagement of the actuating means or motor 88 from the particular machine tool that is to be placed into operation.

While I have shown a particular arrangement of a specific structure, I do not want to limit myself to the particular arrangement shown, for in the operation of my device, many changes in the form and configuration of the component parts may be made without affecting the operativeness of the device, and without departing from the spirit of my invention or the scope of the appended claims.
